When a precombustion chamber type Diesel engine is operated under light loads and at low speeds, it is observed that the ignition flames in its main combustion chamber are generated in several stages under specific conditions of fuel injection. The authors, by observing the multistage ignition flames through an optical fiber probe inserted into the chamber, confirmed a number of band spectra emitted from some substances and CH radicals, existing in the flames, and have made clear some aspects of the chemical reactions taking place in Diesel combustion.
